Beit known that I` EDWARD ALMERON MOON, a citizen of the UnitedStates, residing at Chicago, in the county of Cook andState of Illinois,'have inventeda new and useful Improvement in. Devices for Converting Motion,`

of which the following is a specification.

My invention relates to machines forchanging reciprocating intoy rotary motion, and has for 1ts object tovprovide convenient devices therefor.

My invention is illustrated in the accompanying drawings, whereinv Figure 1 is a' plan View of ythe device embodying my invention.;A Fig. 2 is a cross-section through the linea: rv. Fig. 3 isa sectional v1ew through theline a z, with the spiral shaft removed.

Like parts are indicated'by the same letter 1n all the figures. 'T u A is a frame or bed-piece, shaped as shown in Figs. 1 and 2. Uponthis bed-piece the op? eratlve parts rest. v Bis a short standard thereon, supporting the vboxing C, a similar standard being placed adjacent to the ily-wheel and supporting a similar boxing, C. 1 Journaled in this boxing C, is the shaft C', upon which the ily-wheel C2 is supported.

D and D are short standards resting on the frame or bed-plate and supporting the boxings Similar standards supporting the boxings D4 D5. In these boxy vings are journaled the shafts E3 E2, each of which has a proj ectingendwhich is made in A theform of a spiral, and lettered, respectively, l E and E.

portions E and E terminate ings'hort shafts E? and E5, whicharejournaled in the boxing's E? At the'op'posite end these spiral E7, which boxingsI are supported iupon short standards similar to the standards D D'. Upon theshaft E2,is placed the pinion K, which meshes with the pinion J on the shaft C', which in turn meshes with the pinion K on the shaftE3. c f f G is asteamecylindenfrom which protrudes the piston H, lhaving the arms N and N,to which are secured, respectively, thev frictionclutches I and I. These clutches, as will be seen by inspection of Fig. 1, are turned inopposite directions, and, asv will be seen by the .space O, and the end p iece,.O

Opposite direction, Lis anA outer sheathy or cylinder containing the inner cylindricalfpor-f tion, L', rigid therewith,'the packing P, the

i description hereinafter, are calculated4 lto op-v erate in opposite directions. f v

R is a sliding cylindrical clutch-piece,- having the aperture R and the'hole S, the flanged linner end, T, and is encircled by the-packing T. N is a central aperture .through the cylindrical portion L'.

The use and operation of my invention are- Vas follows: The shafts having the central spiral .f

portion and their ends circular in cross-sec ings `provided for them, as shown` in Fig,.1,f and the shortshaft to which the fly-wheel 1s tion are mounted, respectively, upon the bear-V 'i attached is mounted upon the bearingfor supporting posts between them, the three pinions f `v K, J, and K meshing. iThe piston His now set in operation by`means of the steam-cylin# der'G in the usual manner, so as that it recip.- rocates backward and forward parallel with the shafts.V 1 To its arms N and N are secured v the `clutches I land l', eachl internally struct;y ured as shown in Fig. 3, while the clutch I is in the opposite vorreversed position,- as yindicated.

in Fig. 1. When the piston moves 'inthe direc-' tionindicated by thearrowin Fig.1,the spiraled" 'f f portion of the shaft passes throughthe aperf tureB, the hole S o f the aperture N', 'andthus through theclutch I and through the clutchpiece R. The hole S, as indicated lin Fig. 3,`

is smaller than the aperture R and N', and is adapted to just receive the spiral shaft. Now,

when the motion in the direction of the arrow is impartedvto the clutch I' and the spiral f l shaft passes through the hole S by reason of I the friction between thefsides of the said shaft;

and the sides andedge'sof the hole S, the l clutch-piecev E is forced back, so that its en-Y larged end T rests against the packing-ring P, thereby being locked in position yso as" netto rotate within the clutch proper, I.'- The fur.-

ther motion of the clutch Iin the direction of the arrow -will of coursek cause the shaftto rotate so long as its spiraled portion is within",

A, v4 same as in the clutch I, though 'turned in the* rool thehole S, which is until* the end of thestroke. l;

Y Thus the shaft E3 is rotated and pinion K is put in motion, thus imparting motion to the short shaft and to the fly-wheel, from which motion is communicated by belt or crank, as it may be desired, so that the reciprocating motion of the steamengineis transformed into the rotary motion of the fly-wheel. The reverse motion of the steam-cylinder piston carries the friction-clutch Iin the opposite direction and immediately frees the iange T from the packing-ring P, so that, instead of the shaft rotating, the clutchpiece It will rotate within the end piece, O. During this action of the clutch I the clutch I will of course operate its shaft, as they are set so as to reverse. As seen by inspection, the spiraled portions of the two shafts are spiraled in opposite directions, so that the operation of both shafts and both pinions K and K is to drive the pinion J always in the same direction; hence continuous rotary motion is imparted to the Iiy-wheel C2.

Relative to some of the parts shown in Fig. 1, I have not entered upon any elaborate descri ption thereof, for the reason that said parts are too well known to require description.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, is as follows:

In a device for transforming reciprocating K into rotary motion, the combination of a piston for imparting reciprocating motion with two spiraled shafts journaled parallel with the reciprocating part, two clutches, one on each spiral shaft, set so as to operate the shafts, one while moving in one direction, the other inthe other, both of said clutches being secured to the reciprocating part, and suitable pinions, shafts, and wheels, whereby the rotary motion of the spiral shaft is communicated, so as to impart a continuous rotary motion to a ilywheel.
